Description

Technical Field

[0001] This utility model relates to the field of electricity metering boxes, specifically an electricity metering box with an impact-resistant structure. Background Technology

[0002] An electricity metering box is an enclosed electrical enclosure used to house and protect electricity metering devices and their auxiliary components. It is typically installed in residential, commercial, or industrial power distribution points to fix and connect electricity meters, current or voltage transformers, circuit breakers, fuses, terminals, guide rails, and busbars, among other measuring and protection components. It serves to accurately record user electricity consumption for billing and energy management, while also providing necessary electrical isolation, overload and short-circuit protection, grounding, and safety protection functions. It facilitates meter reading, maintenance, and replacement of metering equipment and meets environmental requirements such as dustproofing, moisture-proofing, and corrosion resistance. The metering box's structure must comply with electrical installation specifications and metering management standards, and it must have clear numbering and sealing locations to ensure the reliability of metering data. During installation, attention should be paid to the correct phase sequence and transformer ratio with the power supply line, reliable grounding, and mechanical fixing. Maintenance space and heat dissipation channels should be reserved to ensure metering accuracy, personnel and equipment safety, and the normal operation of the power distribution system.

[0003] In traditional electricity metering box designs, electricity metering devices are typically exposed to the external environment, making them susceptible to damage from external impacts, vibrations, or improper operation. This is especially true during transportation, installation, or use, where such devices are prone to damage, affecting normal operation and potentially leading to incorrect electricity metering. Furthermore, existing designs lack effective protective measures to mitigate external impacts and pressures, resulting in direct damage to the precision components inside the device. Therefore, this invention designs an electricity metering box with an impact-resistant structure to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an energy metering box with an impact-resistant structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An energy metering box with an impact-resistant structure includes a mounting plate and energy metering devices fixed to the mounting plate. A protective shell is fixed to the outer wall of the mounting plate. An outer iron shell, serving as the outermost protective frame, is provided on the outer side of the protective shell. The lower end of the protective shell is fixed downward to the inside of the iron shell by fixing bolts, forming a first and second protective layer with the iron shell. A first spring plate is fixed to the left and right ends of the protective shell, and a second spring plate is provided at the left end of the first spring plate. A side wall aluminum rod is fixed to the left end of the second spring plate and is fixed to the inner wall of the iron shell. A first rear wall aluminum rod and a second rear wall aluminum rod are arranged at the rear end of the iron shell, with a fixing rod and a rear wall aluminum support rod in between. Side wall aluminum support rods are provided at the front and rear ends of the side wall aluminum rods. A box door is hinged to the front end of the iron shell, and a door aluminum frame and a door protective rod are fixed to the inner wall of the box door. The aluminum rods and the fixing rod constitute a square impact-resistant mechanism, and the first to fourth spring plates are arranged side by side as a buffer protective layer.

[0006] Optionally, a fixing bolt is installed at the lower end of the protective shell. The fixing bolt is fixedly installed downward on the sheet metal shell, so that the protective shell is fixedly installed inside the sheet metal shell by the fixing bolt, thereby defining the positional relationship between the protective shell and the sheet metal shell in the vertical direction.

[0007] Optionally, the first and second spring plates are grouped and distributed on the left and right sides of the protective shell, the upper end of the protective shell is fixedly installed with a third spring plate, the upper end of the third spring plate is installed with a fourth spring plate, and the upper end of the fourth spring plate is connected to the side wall aluminum rod distributed on the top of the iron shell, so that the spring plates form a horizontal and vertical buffer protection layer on the square anti-impact mechanism.

[0008] Optionally, sidewall aluminum support rods are fixedly installed at both ends of the sidewall aluminum rod. The sidewall aluminum support rods are vertical and perpendicular to the longitudinal direction of the sidewall aluminum rod at a 90-degree angle, so that the sidewall aluminum rod and the sidewall aluminum support rods jointly support the square anti-impact mechanism.

[0009] Optionally, multiple sets of first rear wall aluminum rods and second rear wall aluminum rods are fixedly installed at the rear end of the sheet metal shell. A fixed rod with a cross structure is fixedly installed between the first rear wall aluminum rods and the second rear wall aluminum rods. A rear wall aluminum support rod is fixedly installed in the middle of the multiple sets of first rear wall aluminum rods and second rear wall aluminum rods. The first rear wall aluminum rods, second rear wall aluminum rods, fixed rods and rear wall aluminum support rods together form an impact-resistant structure for the rear space.

[0010] Optionally, the front end of the sheet metal shell is hinged to a door, and an aluminum frame and a protective rod are fixedly installed on the inner wall of the door. The aluminum frame is a square frame, and the protective rod is a reinforcing rod of the aluminum frame to provide reinforced protection for the relatively weak structure of the door.

[0011] Optionally, multiple sidewall aluminum rods are fixedly installed on the inner wall of the sheet metal shell, and multiple sets of first and second spring plates are distributed on the left and right sides of the protective shell. The fourth spring plate is connected to the sidewall aluminum rods distributed at the top of the sheet metal shell, so that the sidewall aluminum rods are arranged longitudinally on the inner wall and cooperate with the rear aluminum rods to bear the impact force through the sidewall aluminum support rods.

[0012] Optionally, the protective shell is the first protective layer of the power metering device, the sheet metal shell is the second protective layer, the first spring plate, the second spring plate, the third spring plate and the fourth spring plate are mounted on the square anti-impact mechanism as a buffer protective layer, and the side wall aluminum rod, the first rear wall aluminum rod, the second rear wall aluminum rod, the fixing rod, the side wall aluminum support rod and the rear wall aluminum support rod together form a square anti-impact mechanism to reduce the transmission of external impacts to the power metering device.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the square anti-impact mechanism composed of the side wall aluminum rod, the first rear wall aluminum rod, the second rear wall aluminum rod, the fixing rod, the side wall aluminum support rod, and the rear wall aluminum strut disperses and transfers the external impact force through the cross and longitudinal aluminum rod frame, thereby reducing the impact concentration and protecting the power metering device in the rear space.

[0014] 2. In this utility model, the first spring plate, the second spring plate, the third spring plate and the fourth spring plate are mounted on the square anti-impact mechanism as a buffer protective layer, so that the impact energy is first absorbed by the spring plates and then delayed during transmission. Combined with the double-layer protective structure of the protective shell and the iron shell, as well as the door aluminum frame and door guard rod of the box door to strengthen the local impact, the overall impact resistance of the equipment is comprehensively improved during transportation, installation and use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-7In this embodiment of the utility model, an energy metering box with an impact-resistant structure is provided. An energy metering device 2 is fixedly mounted on a mounting plate 1, which forms the structural support base for the energy metering device 2. A protective shell 3 is fixedly fitted onto the outer wall of the mounting plate 1, serving as the first protective layer for the energy metering device 2. A sheet metal outer shell 4 is installed on the outside of the protective shell 3, serving as the outermost protective frame. Multiple side wall aluminum rods 8, a first rear wall aluminum rod 11, and a second... are fixedly arranged on the inner wall of the sheet metal outer shell 4. The two rear wall aluminum rods 12 form the frame skeleton of the rear space. The lower end of the protective shell 3 is fixed downward to the inside of the iron shell 4 by fixing bolts 5, so that the protective shell 3 and the iron shell 4 are positioned relative to each other in the vertical direction, thereby limiting the working space of the spring plate. The box door 16 is hinged to the front end of the iron shell 4. The door aluminum frame 17 and the door protective rod 18 are fixed to the inner wall of the box door 16, so that when the box door 16 is subjected to local impact, the door aluminum frame 17 and the door protective rod 18 will first share the force and transfer it to the iron shell 4. The composition and connection of the side wall aluminum rods 8, the first rear wall aluminum rods 11, the second rear wall aluminum rods 12, the fixing rods 13, the side wall aluminum support rods 14, and the rear wall aluminum struts 15: Multiple side wall aluminum rods 8 are longitudinally fixed to the inner wall of the sheet metal outer shell 4. Side wall aluminum support rods 14 are fixedly installed at both ends of the side wall aluminum rods 8. The side wall aluminum support rods 14 are vertical and perpendicular to the longitudinal direction of the side wall aluminum rods 8 at a 90-degree angle. The side wall aluminum rods 8 and the side wall aluminum support rods 14 work together to support the lateral load of the square anti-impact mechanism. Multiple sets of first rear wall aluminum rods 11 and second rear wall aluminum rods 12 are fixedly arranged from top to bottom at the rear end of the sheet metal outer shell 4. A cross-shaped fixing rod 13 is fixedly installed between the rear wall aluminum rod 11 and the second rear wall aluminum rod 12. A rear wall aluminum support rod 15 is fixedly installed in the middle of multiple sets of first rear wall aluminum rods 11 and second rear wall aluminum rods 12. The first rear wall aluminum rod 11, second rear wall aluminum rod 12, fixing rod 13 and rear wall aluminum support rod 15 together constitute the impact-resistant structure of the rear space, so that the external impact force is dispersed and transmitted through multiple paths through the cross and longitudinally connected aluminum rod network. The above-mentioned aluminum rods and fixing rods 13 form a square impact-resistant mechanism in combination, so that the impact force is transmitted, dispersed and redistributed within the frame. Arrangement and synergistic effect of the buffer layer: The first spring plate 6 is fixedly installed at the left and right ends of the protective shell 3 respectively. The second spring plate 7 is provided at the left end of the first spring plate 6. The third spring plate 9 is fixed at the upper end of the protective shell 3. The fourth spring plate 10 is installed at the upper end of the third spring plate 9. The first spring plate 6 to the fourth spring plate 10 are arranged in parallel and connected in a longitudinal and transverse manner on the square anti-impact mechanism, so that the spring plates absorb, buffer and delay the conduction of impact energy in the impact transmission path. As a result, most of the instantaneous impact is attenuated at the spring plates and will not directly concentrate on the power metering device 2. The upper end of the fourth spring plate 10 is connected to the side wall aluminum rod 8 distributed at the top of the iron shell 4, so that the longitudinal buffer and lateral support form a continuous buffer link. Function and assembly of door body and box door 16: The front end of box door 16 is hinged to the sheet metal shell 4. During assembly, the aluminum frame 17 of the door body and the door protective rod 18 are fixed to the inner wall of box door 16. The aluminum frame 17 of the door body is a square frame and the door protective rod 18 is a reinforcing rod, so that when the door body is subjected to local external force, the impact is first dispersed by the aluminum frame 17 of the door body and the door protective rod 18, and then transmitted to the sheet metal shell 4 and the square anti-impact mechanism through the hinge, so as to protect the internal power metering device 2. Specific implementation steps and working process example: In this embodiment, the power metering device 2 is first fixed to the mounting plate 1. Then, the mounting plate 1 together with the power metering device 2 is placed inside the protective shell 3 and the outer side of the protective shell 3 is covered with a sheet metal shell 4. The protective shell 3 is fixed downwards inside the sheet metal shell 4 by fixing bolts 5, so that the protective shell 3 is fixed in the vertical direction and the relative position between the spring plate and the aluminum rod is stable. Then, the first spring plate 6 and the second spring plate 7 are installed on the left and right sides of the protective shell 3. The third spring plate 9 is fixed in sequence at the upper end of the protective shell 3 and the fourth spring plate 10 is installed. Multiple side wall aluminum rods 8 are arranged and fixed longitudinally on the inner wall of the sheet metal shell 4. The side wall aluminum rods 8 are connected to the fourth spring plate 10. The front and rear ends of the side wall aluminum rods 8 are fixed to the side wall aluminum support rods 14. Multiple sets of first rear wall aluminum rods 11 and second rear wall aluminum rods 12 are arranged from top to bottom at the rear end of the sheet metal shell 4, and the rear wall aluminum rods are connected in a cross structure by fixing rods 13. The middle part is then fixed. A rear wall aluminum support rod 15 is fixed, and the door 16 is finally hinged. The door aluminum frame 17 and door protective rod 18 are fixed on the inner wall of the door 16. During use, when the iron shell 4 or the door 16 is subjected to transportation or external impact, the impact force is first dispersed by the door aluminum frame 17 and door protective rod 18 through the door 16, and then transmitted along the iron shell 4 to the square anti-impact mechanism composed of the side wall aluminum rod 8, the first rear wall aluminum rod 11, the second rear wall aluminum rod 12 and the fixed rod 13. Due to the cross structure of the fixed rod 13 and the cooperation between the rear wall aluminum support rod 15 and the side wall aluminum support rod 14, the impact force is dispersed in multiple directions in space, thereby reducing the instantaneous stress transmitted to the protective shell 3 and the power metering device 2. At the same time, the first spring plate 6, the second spring plate 7, the third spring plate 9 and the fourth spring plate 10 first buffer and absorb energy on the impact path and prolong the energy transmission time, thereby protecting the power metering device 2 from direct impact or vibration damage. Inspection and Installation Tips: During installation or inspection, the door 16 should be disassembled first, and then the aluminum frame 17, door guard rod 18, rear wall aluminum support rod 15, fixing rod 13, and related aluminum rods on the side wall should be disassembled one by one in the reverse order. This is to facilitate the replacement or inspection of the power metering device 2 and the mounting plate 1 while ensuring that the positional relationship of each aluminum rod and spring plate remains unchanged. The fixing bolt 5 is used to stabilize the position of the protective shell 3. Therefore, when resetting the protective shell 3, the fixing bolt 5 should be reliably installed so that the relative positional relationship between the protective shell 3 and the sheet metal shell 4 is maintained, thereby ensuring the effectiveness of the spring plate buffer layer. In summary, this specific embodiment, without departing from the component composition and connection relationship defined in the claims, details the assembly method and working principle of each component. It also elaborates on the structural positions and collaborative protective functions of core components such as the protective shell 3, the sheet metal shell 4, the first spring plate 6 to the fourth spring plate 10, the side wall aluminum rod 8, the first rear wall aluminum rod 11, the second rear wall aluminum rod 12, the fixing rod 13, the side wall aluminum support rod 14, the rear wall aluminum support rod 15, the door 16, the door aluminum frame 17, and the door protective rod 18. This ensures effective buffering and dispersion of external impacts during transportation, installation, and use, protecting the integrity and metering reliability of the power metering device 2.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
